There are several ways of creating one of these "bots" (Twitter robots, automated accounts) - you don't need to know how to program and you don't need your own server.
Probably the easiest way to set up such a Twitter account is to use the free IFTTT service (which stands for 'IF This, Then That'). If a website has an RSS feed (look for an orange square icon with a radiating white pattern) then you can use that to set up a system that will ping out a tweet for you.
You will need
- an input, in this case an RSS feed
- an output - a spare Twitter account
The steps are
- Create your spare Twitter account and log in
- Create an IFTTT account and log in there too
- While logged into both IFTTT and Twitter go to https://ifttt.com/twitter and activate Twitter as a channel (this will be your output) you probably won't need to activate RSS as a separate channel but just in case its https://ifttt.com/feed
Here’s what it looks like under the bonnet with the RSS feed as the ‘trigger’ causing the action of sending out a tweet. I’ve added the hashtag #filmmusic and asked the recipe to publish this along with the title of the update from Movies in Concert along with the address (Entry URL) and the first line of the page.#filmmusic: (Brooklyn, New York / USA) 07.10.2015 - Doctor Who Symphonic Spectacular http://t.co/DV0E1kByrn The Doctor Who Symphonic Spec…— Movies in Concert (@moviesinconcert) May 2, 2015
